Chemical Structure

3-Carboxy-4-fluorobenzeneboronic acid pinacol ester, 97% CAS 882679-10-9 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO supplies 3-Carboxy-4-fluorobenzeneboronic acid pinacol ester, 97% (CAS 882679-10-9), a certified reference material (molecular formula C13H16BFO4, MW 266.07 g/mol) for analytical method development and quality control.

Structurally, 3-Carboxy-4-fluorobenzeneboronic acid pinacol ester, 97% (C13H16BFO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 266.07 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
